These "preform" geocache tubes are the early stage of a 2 liter soda bottle. They are virtually indestructable, dishwasher safe, and they are clear so you can see everything inside. (All preforms have a very slight greyish tint) Caps are included.

Wish they had a washer or other device to make it waterproof...still a great product.

Preforms

My first purchase of a preform. Indestructible. Waterproof. Only if they were muggleproof. :) Thanks.

Much tougher than I expected

I bought some of these for myself and some to give away. They are much tougher than I expected. I guess they heat these up to make a two litre bottle as the bottles are thin and can be pressed in, but these preforms can't.

I think a car could drive over this and it wouldn;t break. This will make a great cache that will survive the elements without any worry.
